That's When Your Heartache Begins - Elvis Presley

If you find your sweetheart

In the arms of a friend

That’s when your heartaches begin

When dreams of a lifetime

Must come to an end

That’s when your heartaches begin

Love is a thing

You never can share

If you bring a friend

Into your love affair

That’s the end of your sweetheart

That’s the end of your friend

That’s when your heartaches begin
